摘　　要：目的:探讨特发性正常压力脑积水(INPH)的结构影像学特征。方法:对30例确诊的INPH患者磁共振成像进行结构影像学特征分析。结果:30例INPH组Evans指数为(0.32±0.12),胼胝体角(CA)为(69±10)°,颞角宽度(THW)为(7.2±2.1)mm;不对称性蛛网膜下腔增宽性脑积水(DESH)阳性率为83%(25/30);侧脑室周围高信号(PVH)和深部白质高信号(DWMH)平均分为1.9和1.5;中脑导水管流空阳性率为60%(18/30)。结论:结构影像学有助于INPH的诊断。Objective This study was intended to explore the structural imaging features of the Idiopathic normal pressure hydrocephalus.Methods The structural imaging features on the magnetic resonance imaging of 30 patients with confirmed INPH were analyzed.Results The Evans Index of the patients is(0.32±0.12),the callosal angle(CA)is(69±10)°,the temporal horn’s width(THW)is(7.2±2.1)mm;the positive rate of disproportionately enlarged subarachnoid space hydrocephalus(DESH)is 83%(25/30),the mean value of periventricular hyperintensity(PVH)and deep white matter intensity(DWMH)is respectively 1.9 and 1.5,and the positive rate of midbrain aqueduct emptying is 60%(18/30).Conclusion Structural imaging is conducive to the diagnosis of INPH.
